Las preguntas y pruebas de la entrevista de Scala

Aunque algunos directores de recursos humanos están seleccionando a sus candidatos mediante exámenes en papel o pizarra, estos exámenes no deben ser tratados como indicadores válidos del rendimiento futuro. Para evaluar las habilidades de codificación, se necesita un proceso objetivo y repetitivo basado en pruebas que reflejen lo más fielmente posible el primer día de trabajo. Elija las preguntas y pruebas de la entrevista de la DevSkiller Scala y pruebe a sus candidatos a distancia.

Hay muchas características que pueden ser útiles. Por ejemplo, puede pedirle a su candidato que se tome una foto de sí mismo para asegurarse de que no hace trampas. Además, puede tener una entrevista en línea directamente en la plataforma utilizando la función de par de códigos, que le permite tener una idea de cómo es trabajar con sus candidatos.

Las preguntas y pruebas de la entrevista de Scala son desarrolladas por los mejores expertos en el lenguaje de programación de Scala. Esto significa que están diseñados específicamente para comprobar la competencia de sus candidatos en ese idioma en particular.

What to look for in a Scala developer

It can be incredibly difficult to find a good Scala developer. This is because the language has a more complicated syntax than Java or C#, resulting in a particularly steep learning curve that can put many developers off.  Our Scala interview questions and tests will go a long way to helping you in that regard, but it will be very helpful if you know what to look out for.

Scala is a general-purpose programming language providing support for functional programming and a strong static type system. It is mainly used in the backend development of concurrent applications. The key advantages of Scala over other languages are that it is much less error-prone and can perform more kinds of tasks than languages with more basic type systems. While other languages only work with one or two programming styles, Scala works with all three- functional, object-oriented, and imperative programming. This means that a developer working only with Scala can perform more types of tasks without having to switch to a different programming environment. 

Scala uses the same runtime environment as Java, meaning a developer can use Scala libraries for Java applications and Java libraries for Scala applications. This gives Scala developers a huge advantage over other developers because they can access the incredibly large and diverse Java ecosystem.

To find a good Scala developer you are really looking for the elite. Due to its complexity, Scala developers often possess official certificates to prove their aptitude in the language. 

Otherwise, you can expect a good Scala developer to know about pattern matching, as Scala has a built-in general pattern-matching mechanism. They should also possess knowledge of case classes, which are unique to Scala. 

Due to Scala’s compatibility with the Java libraries, your Scala developer should be familiar with the Java open source libraries and be able to tell you which ones they prefer to use. They should also be able to show commercial experience they have gained within the past 2 years and be able to describe the technologies in which they have a functional working knowledge.

Want to customize Scala interview questions and tests?

DevSkiller Scala interview questions and tests are completely adaptable and can be customized to suit your company’s requirements. Our tests come programmed with default settings, but if you want to go one further, you can choose the programming language being assessed and the amount of time each test will take to complete. All while monitoring tests in real-time.

Preguntas frecuentes

¿Qué es RealLifeTesting?

La prueba de la vida real methodology is the foundation of our Scala interview questions and tests. The program is designed to simulate the kinds of real, everyday scenarios that a Scala developer would likely encounter in their daily work. This unique form of developer testing allows recruiters to gain a comprehensive understanding of an applicant’s skill set. The weaker candidates will be identified and eliminated. Only those most adept are able to demonstrate the understanding and knowledge required to be able to progress through to the next stage. 

¿Cuánto tiempo se tarda en montar DevSkiller?

Setting up DevSkiller Scala interview questions and tests takes no time at all. Once you have created your account, tests can be ready to send out to candidates in as little as 5 minutes. DevSkiller’s database stores an extensive library of Scala interview questions, meaning all you need to do is send out the test invites. 

¿Qué haces con el plagio?

We want to be sure that our results can be trusted. The advantage of the DevSkiller model is that our Scala interview questions and tests are assessed automatically. The DevSkiller testing platform implements strict anti-plagiarism tools to ensure test authenticity.
